I am using the function below: public function encodeHtml($responseData) {

    $htmlResponse = "<table border='1'>";
    foreach($responseData as $key=>$value) {
            $htmlResponse .= "<tr><td>". $key. "</td><td>". $value. "</td></tr>";
    }
    $htmlResponse .= "</table>";
    return $htmlResponse;       
}

What is wrong I am doing here. Please help me out.

Answer 1

You're trying to print whole object as string here: $htmlResponse .= "<tr><td>". $key. "</td><td>". $value. "</td></tr>"; $htmlResponse .= "<tr><td>". $key. "</td><td>". $value. "</td></tr>";

You should print every object variable separately, eg to print first_name of actor: $htmlResponse .= "<tr><td>". $key. "</td><td>". $value->first_name. "</td></tr>"; $htmlResponse .= "<tr><td>". $key. "</td><td>". $value->first_name. "</td></tr>";

Answer 2

When using foreach from responseData you get each elemt. So the value gonna be a class and when

$htmlResponse .= "<tr><td>". $key. "</td><td>". $value. "</td></tr>";

The $value is a class wich is as the error said can not be converted to a string.
